ARCHIE H. GRAMPTON, OF CHICAGO, ILLINOIS.

LATCH. E

To all whom it may concern: I

Be it known that I, ARCHIE H. CRAMPTON, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Latches, of which the following is a specification.

This invention relates to improvements in latches and more particularly to pressure latches and its object is to-produce a latch of this class for general use although peculiarly for use on refrigerators and similar containers.

Another object is to produce a latch of this class that is very simple in construction, cheap to manufacture, that is simplicity itself in operation and that, withal, p ossesses the maximum eflicie cy.

The latch comprises akeeper having a resilient pocket which serves as a shock absorber as it receives the locking bolt thus effectually arresting all pounding or jolting incident -to slamming the door; the keeper and bolt tend slightly to throw the door outward or into open position thus relieving the door hinges of some of the strain incident to the "weight of the door and keeping the door primed for instantaneous openmg. I

A further object of the device is to produce a latch provided with a one-piece metal operating handle fulcrumed upon a centerof-motion pin within the latch casing, said handle having, crimped or stamped thereon, a one piece metal 'sleeve. r

With the foregoing and other objects in view the invention consists in the combination and arrangement of parts to be hereinafter fully described in the following specification, pointed out in the appended'claims and clearly illustrated in the accompanying drawings which form a part of said specification and in which Figure 1 is a side elevation of my improved latch showing its application, the latch and door being shown in open position in full lines, and in closed position in dotted lines. Fig. 2 is a plan view. Fig. 3 is a vertical sectional'view, closed position. Fig. 4: is asimilar view in open position,the dotted lines showing the normal position of the handle after the latch has been opened. Fig. 5 is an inverted plan view of the latch.

Like reference characters indicate corresponding parts throughout the several views.

The reference numeral 1 denotes a door and '2 the door jamb. I

Application filed September 4, 1915. Serial No. 49,023.

My improved latch comprises the outer flanged casing 3 adapted to be suitably secured to the door 1, the casing being formed with an opening 4 in one end. Within the casing 3 a casing 6" is disposed which is formed with openings in alinement with the openings specified in the outer casing, said inner casing being formed essentially with :lateral ears 7, 8 the former being perforated in alinemenif with similar perforations in the outer casing to receive the pin .9; and the latter ears being formed with elongated openings 10' to permit the device to be assembled and to permit insertion of the bolt 11, said opening 10 being somewhat larger than alined perforations in the outer casing; the ears 7, 8 and the ends of the casing 6 resting against the door. The inner casing, further, is formed with a longitudinal opening 12 in one end, and an inwardly extending finger 14 serves as a stop fingerin a manner to be hereinafter brought out. i

The handle 15 is fulcrumed upon the pin 9 and extends through the alined openings in the ends of the outer and inner casings and is formed with an angular inner termination 16-which is adapted for engagement with a link 17 also fulcrumed upon the pin 9 and about said link a coil spring 18 is disposed which at oneend abuts said pin. 9 and which abuts a shoe 19 at its'other end, which shoe is slidably arranged upon said link and is formed with an angular termination adapted for engagement with the door 1 when the latch is closed. A yoke 20, the ends of which extend through the bolt 11, passes through. the link 17 and is in frictional engagement with the face of the shoe 19 wherebydt is yieldin'gly retained against the adjacent end of said link, one of the ends of said yoke being disposed in the plane of and capable of engagement with the stop 14 when the latch is open whereby the move- "ment of said yoke is limited.

longitudinally of said link thus moving the shoe 19 longitudinally of said link and comressing the spring 18 and at the same time rotating the bolt 11 and causing the free end thereof to travel over one side of the pocket and into position shown, full lines, Fig. 2. As the link 17 moves toward the door it carries the shoe with it and the same encoun ters the surface of the door just previous to 1 contact of one of the ends of the yoke with the stop 14, the shoe and its connection serving as a shock absorber.

ted, Fig. 4. To close the latch the door may be slammed and the bolt through contact with the keeper will be turned thus raising the yoke andlink and the spring will force these'members together with the shoe into normal position.

What is claimed is 1. In a latch, an outer'casing, an inner casing, a bolt extending through and beyond fulcr'umed on said pin, a link fulcrumed on said 'pin for engagement with one end of said handle, a member slidably arranged upon said link, a flexible member encircling 'said link and abutting said pin and sliding member for yieldingly keeping them the maximum distance apart, a yoke extending through said link in frictional engagement with said sliding, member and terminally embedded in the said bolt and a keeper for said bolt. I I 2. In a latch, an outer casing, an inner casing; a bolt extending through and beyond said casings, a pin connecting said casings, a handle extending intosaidcasings and fulcrumed on said pin, a link fulcrumed .on said pin for engagement with one end of said" handle, a member slidably arranged upon said link, a flexible memberyencircling said link and-abutting saidv pin and sliding maximum distance apart, a yoke extending through said link and in frictional engagement with said sliding member and terminally embedded 'in saidbolt, and a keeper formed with a resilient pocket to 'receive' 1 said bolt, L

3. In a latch, an outer casing, an innercasing, a bolt extending through and beyond 'said casings, a pin connecting said casings, a handle extendlng into said casings and fulcrumed on said pin, a link fulcruined on said pin for engagement with one end of said handle, a member slidablyarranged upon said link, a flexible memlier-encirclingj said linkand abutting said pin and sliding member for yieldingly keeping themf the The handle will. now gravitate intothe position shown dotformed with nesses.

4. In a latch, a perforated outer casing, an inner casing formed with inwardly extending lugs vperforated in alinement with t the perforations in. said outercasing, a bolt extending through alined perforations in said casings, a pin extending through alined perforations in said casings, a handle extending into said casings and fuicrumed on said pin, a link fulcrumed on said pin for engagement with one end of said handle, a

6. In adoor latch, anouter casing, an inner'casin'g, a bolt for said casings, a pin connecting said casings, a yoke carried by said bolt, resilient shock-absorbing means -fulcrumed on said pinfand operatively engaging said yoke" whereby thesame and'said bolt are yieldingly retainedin adjusted relation, manually operable means fulcrumed shoe slidably arranged on said link, a spring on said pin for moving said resilient shoc'kabsorbing means and connections from closed to open position and a keeper formed with a resilient pocket toreceive said bolt;

In testimony that I claim the foregoing as my 'own I have hereto affixed my signa- .ture in the presence of'two subscribing wit.-
